European Radiology, 1997
The image quality of a radiograph is determined by the local contrast, spatial resolution, latitude and the image noise. The goal of digital processing is to improve the visualisation of pathology by optimising these physical parameters. Processing parameters need to be chosen correctly in order to overcome the inverse relationship between contrast and

Veterinary Radiology & Ultrasound, 2008
Image processing or digital image manipulation is one of the greatest advantages of digital radiography (DR). Preprocessing depends on the modality and corrects for system irregularities such as differential light detection efficiency, dead pixels, or dark noise. Processing is manipulation of the raw data just after acquisition.

Otolaryngologic Clinics of North America, 2002
The digital camera has become a valuable component of the clinical practice for many otolaryngologist head and neck surgeons. Because several technical details distinguish digital cameras from their standard 35-mm counterparts, having some knowledge of these features is crucial for integrating digital imaging successfully into a practice.

Veterinary Clinics of North America: Small Animal Practice, 2009
Medical imaging is rapidly moving toward a digital-based image system. An understanding of the principles of digital imaging is necessary to evaluate features of imaging systems and can play an important role in purchasing decisions.

Catheterization and Cardiovascular Interventions, 1999
This tutorial introduces basic digital image processing concepts. An increasing fraction of fluoroscopic images are handled and processed using digital tools. The quality of an image in digital format depends on both the technical details of the digitization process and on the quality of the starting scene. Digital tools yield images that are difficult

Applied Optics, 1988
A new technique, digital image velocimetry, is proposed for measurement of instantaneous velocity fields of time dependent flows. A time sequence of single-exposure images of seed particles are captured with a high speed camera, and the sampled images are then digitized on an image processor, enhanced, and superposed to construct a multiple-exposure ...

Journal of Audiovisual Media in Medicine, 1995
A previous two-part article by Simon Brown described the acquisition, editing, compression and initial storage of digital images taken in the clinical studio. Due to the higher-than-expected demand for this clinical service, additional factors had to be considered when dealing with large numbers of images.

Veterinary Record, 2009
In certification, establishing that a digital image being examined relates, at a stated time, to the animal being certified is key. Digital medical images are increasingly encountered in practice and the trend is likely to continue.

Seminars in Roentgenology, 2003
Digital imaging consists of digital acquisition modalities, image, and information management systems. All modalities are available to be purchased as digital acquisition devices. Image management has been the domain for PACSs. PACSs are complex systems designed to transmit, store, and display medical images.
